PRDTECTOR MECHANISI FOR LOOMS Filed Aug. 10, 1929 Patented June 2, 1931 UNITED STATES PATENT OFFICE ANTHONY D. GARGOLINSKI, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMPTON' & KNOWLES LOOM WORKS, 015 WORCESTER, LEASSACHUSETTS, A CORPORATION OF MASSACHUSETTS PROTECTOR MECHANISM FOR LOOMS Application filed August 10, 1929.

This invention relates to improvements in protector mechanisms for looms and it is the general object of the invention to provide an improved mounting for the protector finger whereby the latter may be given very delicate adjustments with respect to the protector dagger.

It is customary construction in protector mechanisms to weld the dagger to the rolling or protector rod and to secure the protector finger to the rod by means of a set screw. Due to one cause or another it becomes necessary from time to time to adjust the protector finger relatively to the dagger, but in the constructions heretofore employed considerable difficulty is found at times in attempting to effect a slight adjustment. This is due to the fact that the set screw pits or disfigures' the rod so that when given a slightly different angular position it tends to slip back to I the original position. It is an important object of my present invention to provide a connection between the dagger and the protector finger which is independent of the condition of the protector rod and also inde pendent of any device on the rod which serves to prevent longitudinal movement of the finger relatively to the rod.

It is a more particular object of my present invention to provide a protector finger having a part adjustable with respect to and positioned for direct engagement with the dagger.

With these and other objects in view which will appear as the description proceeds, my

invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings, wherein a convenient embodiment of my invention is set forth,

Fig. 1 is a front elevation of a lay having my invention applied thereto,

Fig. 2 is a detailed vertical section on an enlarged scale on line 22 of Fig. 1, and

Fig. 3 is a horizontal section on line 3-3 of Fig. 2. 7 Referring particularly to Fig. 1 I have shown one end of a lay L having a protector 5Q rod 10 mounted in bearing 11 carried by the Serial No. 384,933.

lay. The rod has welded thereto a dagger 12 which cooperates with a frog 13 supported by the breast beam 14. By means of mechanism not shown but well understood forward movement or movement to the left as viewed in Fig. 2 of the frog will cause stopping the loom.

The lay isprovided with a shuttle box 15 to receive the shuttle S which is held in position by a binder 16. The latter is pivoted as at 17 to the box and its inner end engages will move the binder 16 to the left as viewed in Fig. 2 thereby causing rocking of the finger 18 m a counter-clockwise direction. It is this rocking which is to effect a lowering of the dagger 12 so that thesame will clear the frog 13 as the lay heats up. The-matter thus far described forms no part of my present invention and operates in the usual manner.

In carrying my invention into effect I provide an improved form of connection between the dagger 12 and the finger 18. To accomplish this result I provide the finger 18 with an arm'30, as shown in Figs. 1 and 2, and

extend the same so that it will project over the dagger 12. Passing vertically through said armis an adjusting screw 31 threaded into the arm and held in position by a lock nut 32. The lower end of the screw is provided with a head 33 which normally rests against the strain which it has heretofore been called upon to withstand.

Should it be desired to adjust the angular position of the finger with respect to the dagger, the screw 20 and check nut may be loosened after which thescrew3l maybemoved in the desired position. The lock nut 32 is then set tight against the arm and the screw 20 set tight enough to prevent longitudinal movement of the hub19. The spring will act to hold the dagger up against the head of the adjusting screw 31.

From the foregoing it will be seen that I have provided a very simple connection between the protector finger and the dagger whereby the operating force for the dagger is communicated from the binder independently of the screw 20, thereby subjecting the latter to practical]; no strains. It will further be seen that the adjustment between the binder finger and the dagger may be efiected independently of the condition of the protector rod or the contact which may exist between the same and the screw 20. It will still further be seen that with a moderate setting of the set screw 20 a longitudinal movement of the finger 18 will be prevented relatively to the rod 10 and at the same time allow angular movement of these two elements with respect to each other.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a protector mechanism for a loom having a protector rod and a shuttle binder, a protector finger mounted on the rod to engage the binder, a dagger secured to the protector rod and moving therewith, means to prevent longitudinal movement of the finger relatively to the rod, and a connection between the finger and the dagger independent of the said means and communicating an operating force from the finger to the dagger.

2. In a protector mechanism for a loom having a protector rod and a shuttle binder, a finger mounted on the protector rod and normally positioned to engage the binder, a dagger secured to and movable with the protector rod, means to prevent longitudinal movement of the finger relatively to the rod, an arm on the protector finger extending in vertical alignment with a portion of the dagger, and adjustable connections between the arm and the dagger communicating the operating force from the finger to the dagge independently of the means, said connect-ions being maintained by the means.

3. In a protector mechanism for a loom having a protector rod and a shuttle binder, a finger mounted on the rod and normally ANTHONY D. GARGOLINSKI.
